Let me tell you a little something about rivetted maille. I started making some today, and after about five hours and ten VERY sore fingers, I've got exactly 145 flattened, UNPUNCHED, UNWOVEN rings. I did manage to get seven 36 inch coils rolled, but only cut one of them up so I could practice my flattening technique. Needless to say getting only 145 useable rings out of the 450 I cut, my flattening skills need a little work (though they were markedly better by the end). So far, the experience has left me convinced of two things: 1. The cost of rivetted maille is completely justified, and 2. making it should be used as a punishment for convicts!
